Embodiment Construction
[0022] In order to further understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the specific embodiments do not limit the protection scope of the present invention.
[0023] like figure 1 As shown, an intelligent actuator for the dilution water of the headbox to control the quantification of the paper banner is mainly composed of a CAN bus controller 3, a stepping motor 4, a dilution water valve position sensor 5, a reduction box 6, and a dilution water valve 7 1. Diluting water valve position indicator 1 and housing 2. The dilution water valve 7 is connected to the lower end of the output shaft of the reduction box 6 through a coupling; the position indicator 1 of the dilution water valve is connected to the upper end of the output shaft of the reduction box 6; the stepper motor 4 adopts a double output shaft structure, and the front output shaft end is installed At the ...

The invention discloses a smart actuator for headbox dilution water used to control paper breadth quantification. A dilution water valve of the actuator is connected with the lower end of an output shaft of a reduction case through a coupling; a step motor is in a double output shaft structure, and the front output shaft end of the step motor is mounted at the input end of the reduction case; the reduction case comprises two transmission pairs, one is a spur gear transmission pair composed of a large gear and a small gear, and the other one is a worm-gear transmission pair composed of a worm and a worm gear; the worm gear is mounted on an output shaft of the reduction case, a case body of the reduction case is provided with a limit pin, the worm gear is provided with a 90-degree mechanical limit groove, a lower mechanical limit corresponds to a 0-degree part of the dilution water valve, an upper mechanical limit corresponds to a 90-degree part of the dilution water valve. The smart actuator is capable of accurately controlling the volume of dilution water added by the dilution water valve, a smallest interval of dilution water control is smaller than 60mm, accurate control of paper local breadth quantification is guaranteed, and paper product quality is improved.
Description
technical field [0001] The invention relates to the technical field of pulping and papermaking, in particular to a dilution water valve actuator for a headbox used in a paper machine to control the lateral quantitative distribution of paper sheets by adjusting the local slurry concentration through dilution water, in particular to a CAN bus-based The advanced dilution water intelligent actuator is suitable for the high-speed paper machine's quantitative control requirements for paper banners. Background technique [0002] For the quantitative control of paper banners, in the mid-to-late 1990s, companies such as Beloit in the United States and Voith in Germany introduced headboxes that control paper banner quantification with dilution water. The slurry banners of the headbox are divided into several partitions. Dilution water is added to different partitions to adjust the slurry concentration of the partitions, thereby changing the dry basis weight of the partitions, and redu...
